Answer:
symmetric matrix is the square matrix and it is equal to its transpose
Step-by-step explanation:
solution
a symmetric matrix is the square matrix and it is equal to its transpose
As A is symmetric matrix then
A = 
here only square matrices will be symmetric
and matrix A is symmetric its mean its matrices have equal dimension
and every square diagonal matrix is also symmetric when all off diagonals element is zero
symmetric matrix for all indices i and j
A = aij = aji
Answer:
A. 72
Step-by-step explanation:
If she is making 12 cobblers and needs 6 peaches per one.
She needs 72 (6 times 12= 72) or ( 6c = 72)
Answer:
120
Step-by-step explanation:
Answer:
Jessica dug 17.85 feet after 3 minutes
Step-by-step explanation:
35 × 0.17 = 5.95 (feet dug in one min.)
5.95 × 3 = 17.85 (feet dug in three mins.)
Let width be x m
perimeter = 2L + 2W
W = x and L = 4W - 7 = 4x - 7
so we have the equation
2(4x - 7) + 2x = 136
8x - 14 + 2x = 136
10x = 150
x = 15
So the width = 15m and the length = 4(15) -7 = 53 m. Answer
